Hi Per, You can tell the compiler to accept custom metadata tags by using the "keep-as3-metadata" compiler flag. You'll have to add it to your compiler options. See http://livedocs.adobe.com/flex/3/html/help.html?content=compilers_14.html for details. I hope that helps. -- david keutgens software consultant cynergy australia web | http://www.cynergysystems.com
